Expression Shortcut Idea:
A shortcut to open the expression would be nice.
If I have a position expression on a layer I would normally use the default expression shortcut (Double E). However, it would be nice to have that shortcut (or a new one created). If I select the layer, then push P (to reveal the position) then push Alt + Ctrl+ A (Which will select all properties that are showing). Then, with that property selected, you could then push the double E shortcut to reveal the expression of that property.
Thank you for submitting this idea.
There is already a shortcut available to add an expression to a selected property: Option + Shift + = (macOS) or Alt + Shift + = (Windows)
The Add Expression command is also available from the Animation menu. The keyboard shortcut can be customized in Edit > Keyboard Shortcuts.
Does this do what you are requesting? If not, please clarify what functionality you’d like to see added to After Effects.

Pressing EE shows only properties with expressions.
